eprovements in firearms, and particularly to a firearm of the type which is aimed by sighting along the barrel at the object yto ,Y

duced scale showing a firearm provided befred upon. e Most ries, Shotguns and similar firearms Y are aimed by sighting along the upper faces of the barrels thereof, and priorfto',` lthis invention much inconvenience has been caused by heat waves whichI arise from said barrels.` This is particularly true in connection with firearms which are fired a great number of times without the lapse of a sufficient interval of'time to permit the barrels of the firearms to cool, such as Shotguns which are f used in thersport of trap shooting. The

passage of'heat waves from the barrel of a firearmL causes a mist to form along the path of sight, which mist interferes with the vision ofthe person using the firearm and prevents accurate aiming of said firearm. 1 v

yPrior tol this invention firearms have been g provided with ribs of various shapes and arrangements which were intended to elimie nate the difficulty mentioned above, but none ofV these ribs functioned in an entirely successful manner.` The present invention contemplatesthe use of a rib which is formed of a material which is impervious to heat, said rib acting to insulate the heated barrel of the firearm from the space-immediate- ;ly above, the rib, whereby the troublesome heat waves mentioned are eliminated from the path of sight anda clear vision of the object aimed at is permitted.

i. With vthe foregoing and otherobjects in view, the invention comprises the novel construction, combination 'and arrangement of parts hereinafter more specifically described fandl illustrated` in the accompanying drawings wherein is'shown the preferred embodi- 1 ment of ythe, invention.r However, itis vto be f understood.- that the invention comprehends `changes', variations andA modifications which come within the scope of the claims here-` with an auxiliary rib Vhaving an inclined topI face.

In the drawing A designates a firearm of the type which is aimed by sighting along the barrel thereof, said firearm 1having the usual stock B, breech C and barrel D. The firearm illustrated in the` drawing is of the repeating type, but as the mechanism which permits repeated firing forms no part of the present invention it will not be described.

The barrel of the firearm shown inthe drawing is provided with an integral rib 1 which extends upwardly from said barrel and is arranged the full length thereof. As

ywill be seen by referring to Figs. I and II of the drawing, that portion of the wall of thebarrel at the rib 1 is substantially thicker than the balance of the wall of the barrel, and formed in this thickened portion of the barrel vis a longitudinally extending dovetail groove 2. The dovetail groove 2 extends from a point slightly removed inwardly from the end of the rib to the extreme inner end of said rib as shown in Fig. III. By

vterminating the dovetail groove short of the outer end of the barrel D an upstanding wall 3 is produced which is intended for a. purpose to be hereinafter set forth.

` 4f designates an auxiliaryl rib which is in cross section the approximate shape of a letter Tthe downwardly extending portion t rearmost end of said groove and said auxiliary rib being moved longitudinally of said groove until the abutment facey 4.98 of said rib contacts with the abutment fac-e Da of said barrel. The auxiliary rib et is of suoli C; length that when said rib is in its proper position and the barrel of the firearm is attached to the stock thereof, the rearmost face of said rib will contact with the front face C. of the breech of the firearm whereby said rib is prevented from being accidentally moved rearwardly, and because the contacting abutment faces 4a and Da prevent said rib from moving forwardly and the "inclined walls of the dovetail groove 2 prevent said rib from movingupwardly, it, is apparent that said. auxiliary rib is securely held in its proper position on the barrel of the firearm.

M The auxiliary rib; i is made from a material which is impervious to heat, such, for instance, vas bakelite, and regardless of the intensity of the heat of the barrel no heat waves will pass upwardly into the path of sight ofthe person aiming the firearm, said auxiliary rib acting as any insulator and keeping Said path of sight absolutely free from the troublesome mist already referred to. Y

.As the temperature of the barrel of a firearm'changes there is a slight expansion and contraction ofthe metal of said barrel. In

'the'use of a firearm constructed in accordance with my invention vthis slight movement may take place without affecting the yauxiliary rib, as the inclined wall of the `groove 2 may move relative to the inclined faces of the portion 4 of the auxiliary rib 4. In this connection it will be necessary to make the auxiliary rib of slightly less length than the groove 2 so that t-he barrel of the firearm may contact longitudinally withbut crushing said rib.

In Fig. IV`IVliaveillustrated the barrel portion of afirearm which is provided with a rib l, said firearm being provided with a "dovetail groove 2a similar to the dovetail groove 2 of the firearm already described.

The firearm illustrated in Fig. IV is provided'with an auxiliary rib la which has a inserted into the dovetail groove 2 of the 1 firearm.

portion so shaped as to be capable of being The auxiliary riblfa is provided with' an inclined top face; in other words, said top face of said rib is a greater distance from the axis of the barrel' at the outer end of said barrel than it is at the end of the barrel adjacent 'to the breech (la of the firearm. `By this arrangement a firearm may be provided with an auxiliary rib which will cause the rearm to be aimed below the I' objects to be fired upon, due to the fact that the person aiming the firearm sights along the top face of the auxiliary rib and if this auxiliary rib is higher at one end, as illustrated in Fig. IV, it will be necessary to I lower the outer end of the barrel of the firearm to sight the object along said top face of said auxiliary rib.

I claim:

l. A firearm having a barrel, and aV rib ex- I from said barrel, and said firearmnbarrel being capable ofV slight movement relative to said rib. v l l 3. A r'earm having a barrel provided with a longitudinally extending groove, and a rib sea-ted in said groove, said rib being formed of a material impervious to heat whereby the space immediately above said rib is kept free from heat waves arising from said barrel.

4;. A firearm having a barrel provided with a longitudinally extending dovetail groove, and a rib seated in said groove, said rib being formed of a material impervious to heat whereby the space immediately above said rib is kept free from heat waves arising from said barrel.

5. A firearm having Aa barrel provided with a longitudinally extending dovetail groove, and a rib approximately T-sh'aped in cross section a portion of which is ada-'pted to` be introduced into said groove, said 4rib being formed of 'a material impervious to heat whereby the space immediately above said rib is free from heat waves arising from said barrel. y

6. A firearm having aV barrel provided with a longitudinally extending groove in its upper face, a rib seated in said groove, means whereby saidvrib is prevented rfrom moving upwardly inl said gro0ve,`and means whereby said rib is prevented from moving longitudinally of said groove, said rib being formed of a material impervious to heat 'whereby the space immediately above said rib is kept free from heat waves arising' from said barrel. y i

7. A firearm having a y barrel provided with a longitudinally extending p dovetail groove in its upper face, a rib a portion of lll) which is seated in Said groove, means comprising abutment faces at the opposite ends of Vsaid barrel whereby said rib is prevented from moving longitudinally of sald groove,

said rib being formed of a material imper-` rib being provided with an inclined top face along which the object being fired upon is sighted. l

9. firearm having a barrel, and a rib extending longitudinally of said rib, said rib being formed of a material impervious to heat and said ri-b being provided with an inclined top face along which the object 20 being fired upon is sighted.

In testimony that I claim the foregoing I hereunto aflix 'In signature.
